Drilling
Hook load
This is the load on the hook this is the summation of the strings, i.e.; the bit and (BHA) bottom hole assembly
Weight on bit
It's always calculated from the hook load and its decrease on it.
Since if the HL is 500 tones and suddenly became 400 tones so -this difference is due to the formation resistance and this is called the WOB.
Sand (lowest resistance) < shale < silt < lime < dolostone < anhydrite (highest resistance)
The higher the FM resistance, the higher the WOB
C) Stand pipe pressure
This is the pressure of the pumped fluids inside the pipes and hoses. This is related highly to the SPM.
D) Casing pressure
This is the pressure of the pumped cement into casings.
E) Rotary speed
The speed of rotation of the strings, which is, supported either from above on top drive or on the rotary table on rig floor.
F) Rotary torque
The resistance of the formation to the drilling and rotation of strings
The more the resistance of formation, the higher exerted torque
G) Pump speed
The speeds of pumping of mud inside the pipes, which depend on the number of, stroke per minute or in general the efficiency of pump.
Drilling fluids
A) Volume
B) Mud Wt (density) into and out from hole
C) Mud temp into and out put from the hole
D) Mud conductivity (resistivity) into and out put from hole
?Q: What are the sensors that feel all those parameters
There are 3 types of the sensors such as
1- Pressure transducer: ANALOUGE
Standpipe pressure sensors
Casing pressure sensors
Hooks load sensors
Torque sensors
Mud weight sensors.
